The Quest for New Technologies
An international team led by researchers at The University of Texas at Dallas and Nankai University in China has discovered a new technology for refrigeration that is based on twisting and untwisting fibers. In research published in the Oct. Ray Baughman , director of the Alan G. Baughman is a corresponding author of the study, along with Dr.
Three Hill Country Ranch Roads, , and , are known throughout Texas as the Twisted Sisters, and riders come from near and far to enjoy them. For me it is near, just a short ride from my home to the first Sister. The first Sister we encounter is Ranch Road , which starts at the north edge of Medina. Following it west, we pass many beautiful ranches, one with its own landing strip and double-size hangar. Right on Highway for a mile brings us back to again, and we turn left and head for Leakey and the next Sister, Ranch Road Had we gone straight on for another three miles we could have visited the Lone Star Motorcycle Museum, a tiny jewel set in the beauty of the Hill Country. Sister twists more on this leg, going up and over a pretty typical Hill Country hill, with lots of quick turns before descending into the Little Dry Frio Creek Valley. This stretch starts off pretty straight, but then bucks and snorts and twists and turns in an effort to throw us like a bull in a Bandera rodeo.
By Jordan Wilkerson. Dallas scientists have developed a fundamentally new approach to cooling things down — by understanding that twisting and untwisting fibers can result in temperature changes. For example, as a thin rubber strand is twisted tightly, the strand gets quite hot. As the rubber untwists, it cools. Researchers at the University of Texas at Dallas affixed fibers such as rubber to a motorized twister that applied a torsional force. The scientists demonstrated their twist on rubber, fishing lines and nickel titanium wire — the same kind of wire used in dental braces. The cooling effect was observed in all of them. In the research paper, the scientists demonstrated the effects of twist, also referred to as torsion, on a very small scale.
